An electronic component mounter where information indicating completion of component mounting is memorized each time a component is mounted on circuit board by suction nozzle. Then, in a case in which mounting work is interrupted by a stoppage of the electronic component mounter and then restarted, the mounting position of the electronic component is imaged by mark camera according to information memorized immediately before the mounting work was interrupted. Also, with the electronic component mounter, in a case in which mounting work is interrupted by a stoppage of the mounter and then restarted, the mark camera is moved along a path over which the suction nozzle moved until the position of the suction nozzle when mounting work was interrupted. Here, imaging of the circuit board is performed by the mark camera.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A mounter comprising: a component holding tool configured to hold a component and mount the held component on a board; an imaging device configured to image any position on a base on which the board is loaded; and a control device including: a path imaging section configured to, in a case in which mounting work is interrupted by a stoppage of the mounter and then restarted, use the imaging device to image the base on which the board is loaded along a path over which the component holding tool moved until a position of the component holding tool when mounting work was interrupted; a dropped component determination section configured to determine whether the component dropped on the base on which the board is loaded based on image data captured by the path imaging section; and a dropped notification section configured to report information to an operator indicating that the component has been dropped in a case in which the component was determined to have been dropped by the dropped component determination section.
2. The mounter according to claim 1 , wherein the control device further includes a holding determination section configured to, in a case in which mounting work is interrupted by the stoppage of the mounter and then restarted, determine whether the component holding tool is holding the component planned to be held after mounting work is restarted, and the path imaging section is configured to, when the holding determination section determines that the component holding tool is not holding the component, use the imaging device to image the base on which the board is loaded along a path over which the component holding tool moved until the position of the component holding tool when mounting work was interrupted.
3. The mounter according to claim 1 , wherein the control device further includes a memory section configured to memorize information indicating completion of mounting of the component on the board for each act of mounting the component on the board by the component holding tool; a mounting position imaging section configured to, in a case in which mounting work is interrupted by a stoppage of the mounter and then restarted, use the imaging device to image a mounting position of the component on the board memorized on the memory section immediately before the mounting work was interrupted; a mounting determination section configured to determine whether the component was mounted at the mounting position correctly based on image data captured by the mounting position imaging section, and an error reporting section configured to report information to an operator indicating that mounting of the component at the mounting position was not correct in a case in which the mounting determination section determines that mounting of the component at the mounting position was not correct.
